Terminations Tackle 10 W to 4 GHz

Aug. 11, 2015
A line of 50-Ω terminations with 4.1/9.5 connectors handles as much as 10 W power through wireless communications bands through 4 GHz.

A line of compact coaxial loads/terminations with 4.1/9.5 (mini-DIN) connectors serves wireless bands through 4 GHz. The 50-Ω loads are supplied with male connectors and  feature low VSWRs of typically 1.10:1 through 2 GHz and 1.20:1 through 4 GHz. As an example, model TMDM1-3 operates from DC to 3 GHz with 1.10:1 typical VSWR through 1 GHz and 1.25:1 typical VSWR through 3 GHz. It handles 1 W average power and 2 kW peak power (a 5-μs pulse at 0.05% duty cycle). It is fashioned with PTFE virgin-grade insulators and handles operating temperatures from -55 to +85°C. The coaxial termination is 1.58 in. in length with 0.92-in. diameter and weighs 1.20 oz.
